Subject: [PATCH 0/5] PCI: Convert pci_resource_to_user() to a weak function

Architectures currently define HAVE_ARCH_PCI_RESOURCE_TO_USER if they want
to provide their own pci_resource_to_user() implementation. This could be
simplified if we make the generic version a weak function. Thus,
architecture specific versions will automatically override the generic one.

Denis Efremov (5):
PCI: Convert pci_resource_to_user to a weak function
microblaze/PCI: Remove HAVE_ARCH_PCI_RESOURCE_TO_USER
mips/PCI: Remove HAVE_ARCH_PCI_RESOURCE_TO_USER
powerpc/PCI: Remove HAVE_ARCH_PCI_RESOURCE_TO_USER
spark/PCI: Remove HAVE_ARCH_PCI_RESOURCE_TO_USER

Subject: [PATCH 5/5] spark/PCI: Remove HAVE_ARCH_PCI_RESOURCE_TO_USER

The function pci_resource_to_user() was turned to a weak one. Thus,
spark-specific version will automatically override the generic one
and the HAVE_ARCH_PCI_RESOURCE_TO_USER macro should be removed.
